Embodiment
Below in conjunction with accompanying drawing the utility model is done further description: shown in Fig. 2-5, a kind of site error inspection jig is made up of localization part and measure portion; Wherein localization part is by anchor clamps floor 1, preceding bearing 2, prelocalization cover 3; Prelocalization support 4, back locating support 12, back locating sleeve 7 and rear support are formed, and measure portion is measured plug 6, ¢ 20 measurement plugs 5, angle measurement degree dial gauge 8 by ¢ 30; Survey eccentric position size dial gauge 9, survey symmetry dial gauge 10, survey verticality dial gauge 11 and form; It is characterized in that: preceding bearing 2 is connected with anchor clamps floor 1 through screw, register pin; Prelocalization cover 3 is connected with preceding bearing 2 with mandrel through bearing, and back locating sleeve 7 is connected with rear support with mandrel through bearing, and rear support is connected with floor 1 through screw, register pin; Prelocalization support 4 also is to be connected with floor 1 through screw, register pin with back locating support 12; All be provided with mutually perpendicular two positioning supports on prelocalization support 4 and the back locating support 12.¢ 30 measure plugs 6 be placed on part treat in gaging hole ¢ the 30 ± 0.002 hole in back locating support 12 on positioning supports be close to; Positioning supports is positioned on the center of measuring plug; All dial gauges all are contained on the corresponding gauge stand, and gauge stand is adsorbed on the floor 1 through magnetic force.The pointer horizontal vertical of angle measurement degree dial gauge is measured the plug axis in ¢ 30; The pointer of surveying eccentric position size dial gauge is upwards perpendicular to measuring the plug axis; Become an angle of 90 degrees with the pointer of angle measurement degree dial gauge; Measurement point equates apart from the distance of plug with datum axis A-B intersection point with positioning supports point apart from the distance of positioning supports point, is 100mm, so just can measure the 1st, 2 error.¢ 20 measure plugs 5 ¢ 30 measure plugs 6 finish the work withdraw from after; Insert part treat in gaging hole ¢ the 20 ± 0.002 hole in and prelocalization support 4 on positioning supports be close to; Make the pointer of surveying the verticality dial gauge and the pointer of surveying the symmetry dial gauge also on level and vertical both direction, become 90 to spend; Positioning supports point is 100mm according to measurement point and also equal apart from the distance of datum axis A-B, so just can measure the 3rd, 4 error.
As shown in Figure 2; The borehole jack of the two ends ¢ 48+0.005 of workpiece is gone on prelocalization cover 3 and the back locating sleeve 7 (note this moment workpiece axially need leave the gap) here; To measure plug 6 insert in ¢ 30 ± 0.002 holes and make it with locating support 12 on mutually perpendicular two positioning supports lean on the jail, thereby realize six point locations of workpiece.Attention: before the measuring workpieces, replace workpiece that angle measurement degree dial gauge 8 is proofreaded with survey eccentric position size dial gauge 9 by top step with calibrating device and make zero for the first time.
Let the positioning supports point be in the design and measure plug 6 middles; Angle dial gauge 8 is used for checking whether the 19 ° ± 30' of Angular Dimension in ¢ 30 ± 0.002 holes is qualified at this moment: if measure the effective length of plug 6 is 200 millimeters; Distance from the middle to the measurement point is exactly 100mm, then: 100*sin30'=0.87mm
That is to say: the positive and negative oscillating quantity of this list index is no more than 0.87 millimeter, and then this error is just not overproof.
Dial gauge 9 is used for checking the eccentric position size 18.55 ± 0.05 in ¢ 30 ± 0.002 holes: because workpiece anti-rotation fulcrum is located at the mid-point that angle ¢ 30 measures plug 6 length; According to similar triangle theory; The reading 1:1 of dial gauge 9 has reacted the off-centre in ¢ 30 ± 0.002 holes and has put the error amount of size 18.55, and it is qualified that the positive and negative oscillating quantity that is to say this list index is no more than 0.05 workpiece.
Above two surveyed after; ¢ 30 is measured plugs 6 unloads down, with ¢ 20 measure plugs 5 insert in ¢ 20 ± 0.002 holes and make it with locating support 4 on mutually perpendicular two positioning supports lean on the jail (same: for the first time before the measuring workpieces by top step with calibrating device replace workpiece will survey symmetry dial gauge 10 with survey verticality dial gauge 11 proofread make zero).Let the positioning supports point be in the middle that ¢ 20 measures plug 5 in the design; At this moment; Dial gauge 10 is used for checking whether the symmetry of ¢ 20 ± 0.002 hole relative datum A-B is qualified: equally according to similar triangle theory; The reading 1:1 of dial gauge 10 has reacted the error amount of the symmetry of ¢ 32 ± 0.002 hole relative datum A-B, and it is qualified to that is to say that the positive and negative oscillating quantity of this list index is no more than 0.1 workpiece.
Dial gauge 11 is used for the error of perpendicularity of measuring workpieces ¢ 20 ± 0.002 hole relative datum A-B: because the anti-rotation fulcrum is located at the mid-point that vertical ¢ 20 measures plugs 5 length; The plug of such 200 millimeters long is divided into two; Length is 100mm just in time; So the reading of dial gauge 11 promptly is the error of perpendicularity value of workpiece, according to the operation requirement, the range of readings of this table is no more than 0.2mm, and then workpiece is qualified.
